Auto re-segmentation to assign new applications in a microsegmented network

1. A non-transitory computer-readable storage medium having computer-readable code stored thereon for programming a computing system to perform steps of:

subsequent to performing auto segmentation on a network that includes a set of policies of allowable and block communications, observing communication between a plurality of hosts on the network;

determining unassigned communication paths based on the observing that are either blocked because of a lack of a policy of the set of policies or because there is no policy of the set of policies for coverage thereof; and

assigning the unassigned communication paths to corresponding policies of the set of policies,

wherein the auto segmentation includes

obtaining network communication information about the plurality of hosts in the network and applications executed on the plurality of hosts; and

automatically generating one or more microsegments in the network based on analysis of the obtained network communication information, wherein each microsegment of the one or more microsegments is a grouping of resources including the hosts and the applications executed on the hosts that have rules for network communication.

2. The non-transitory computer-readable storage medium of claim 1 , wherein the assigning is based on heuristics.

3. The non-transitory computer-readable storage medium of claim 1 , wherein the assigning is performed without reperforming auto segmentation.

4. The non-transitory computer-readable storage medium of claim 1 , wherein the assigning further includes

providing the unassigned communication paths to a user; and

receiving input from the user for the assigning.

5. The non-transitory computer-readable storage medium of claim 1 , wherein each of the communication paths is a flow in the network where the flow is communication between a first application and a second application.

6. The non-transitory computer-readable storage medium of claim 1 , wherein each of the communication paths is a flow in the network where the flow is communication between a first application and a second application, wherein the communication between the first application and the second application was not included in the network communication information.

7. A method comprising the steps of:

subsequent to performing auto segmentation on a network that includes a set of policies of allowable and block communications, observing communication between a plurality of hosts on the network;

determining unassigned communication paths based on the observing that are either blocked because of a lack of a policy of the set of policies or because there is no policy of the set of policies for coverage thereof; and

assigning the unassigned communication paths to corresponding policies of the set of policies,

wherein the auto segmentation includes

obtaining network communication information about the plurality of hosts in the network and applications executed on the plurality of hosts; and

automatically generating one or more microsegments in the network based on analysis of the obtained network communication information, wherein each microsegment of the one or more microsegments is a grouping of resources including the hosts and the applications executed on the hosts that have rules for network communication.

8. The method of claim 7 , wherein the assigning is based on heuristics.

9. The method of claim 7 , wherein the assigning is performed without reperforming auto segmentation.

10. The method of claim 7 , wherein the assigning further includes

providing the unassigned communication paths to a user; and

receiving input from the user for the assigning.

11. The method of claim 7 , wherein each of the communication paths is a flow in the network where the flow is communication between a first application and a second application.

12. The method of claim 7 , wherein each of the communication paths is a flow in the network where the flow is communication between a first application and a second application, wherein the communication between the first application and the second application was not included in the network communication information.

13. A server comprising:

one or more processors and memory comprising instructions that, when executed, cause the one or more processors to

subsequent to performance of auto segmentation on a network that includes a set of policies of allowable and block communications, observe communication between a plurality of hosts on the network,

determine unassigned communication paths based on the observation that are either blocked because of a lack of a policy of the set of policies or because there is no policy of the set of policies for coverage thereof, and

assign the unassigned communication paths to corresponding policies of the set of policies,

wherein the auto segmentation includes

obtaining network communication information about the plurality of hosts in the network and applications executed on the plurality of hosts; and

automatically generating one or more microsegments in the network based on analysis of the obtained network communication information, wherein each microsegment of the one or more microsegments is a grouping of resources including the hosts and the applications executed on the hosts that have rules for network communication.

14. The server of claim 13 , wherein the unassigned communication paths are assigned based on heuristics.

15. The server of claim 13 , wherein the unassigned communication paths are assigned without reperforming auto segmentation.

16. The server of claim 13 , wherein the unassigned communication paths are assigned by

providing the unassigned communication paths to a user; and

receiving input from the user for the assigning.

17. The server of claim 13 wherein each of the communication paths is a flow in the network where the flow is communication between a first application and a second application.
